Carefully conducted studies over many years show the same thing: that our eating habits are almost entirely unconscious, and can be influenced by hundreds of outside factors. While detailing his simple and fascinating studies, Wansink explains how people don't eat calories, they eat volume, how we are manipulated by brand and appearance, and what your favourite comfort food says about you. With an insightful, incredible exploration of what makes us eat the way we eat, Dr. Wansink demonstrates that it's not what we eat - it's how we eat it.
